I'm looking for this book about a girl who goes with her family to live on a reservation for the summer and the Indian gel doesn't like her but
Is it a children's/young teen's book? If so it might be Something to Hold by Katherine Noe. Here is a description:
It's the summer of 1962 and Kitty's father's job as the forest manager for the Bureau of Indian Affairs has landed them on the Warm Springs Reservation in Oregon, where nearly everyone else is NativeAmerican. Kitty Schlick is apprehensive about starting sixth grade. Kitty reluctantly attends yet another new school, an outsider and in the minority as a white person; she eventually befriends brave Jewel, her feisty brother Raymond, and kind Pinky. Still, Kitty has trouble navigating the reservation’s intricate alliances, and she is shocked to find that her teachers and church acquaintances disrespect Indians, perceiving them as drunks and dropouts.
This was published in 2011, so fairly recent--is this what you were thinking of? If not, let me know and give me a couple more clues! We'll track it down.
